Specification of Letters Patent.

Patented Aug. 8, .1916.

Application filed July 15, 1914. SeriaLNo. 851,164.

To all whom it may concern Be it known that I, FREDERICK 1V. W001),citizen of the United States, residing at Jasper. in the county ofSteuben and State of New York, have invented certain new and usefulImprovements in Safety-Razors, of which the following is aspecification.

My invention relates to improvements in safety razors. and as itsprimary 0b]ect aims to provide a safety razor wherein the blade canremain connected with its holder in the frame both for shaving and whilebeing sharpened upon a strep, whereby time, annoyance and injury aresaved, as well as the cost of extra appliances ordinarily required forstropping the blades.

The invention as a. further object contemplates means so arrangedrelatively to the. blade and its support as to permit oscillation of thesame during a sharpening operation.

The above and additional objects are accomplished by such means as areillustrated in their preferred embodiment in the accompanying drawings,described in the following specification and then more particularlypointed out in the claims which are. appended hereto and form a part ofthis application.

In describing my invention in detail reference will be had to theaccompanying drawings wherein like characters denote like. orcorresponding parts throughout the several views, and in which Figure 1is a side elevation of the razor, the blade being shown in a positionready for use: Fig. 2 is a longitudinal sectional view on the line 2-2of Fig. 1; Fig. 3 is a sectional view, the blade being shown in aposition ready to be stropped; and Fig. 4 is a fragmentary view.

Referring now to the drawings by numerals. 1 designates that portion ofthe frame within which the blade 2 is arranged. Said blade 2 is securedin any suitable manner as indicated at 3 to a rotatable shaft likesupport 4, the extremities of which are journaled within the sides ofthe frame 1 as indicated in Fig. 3 of the drawings. Be-

tween the frame sides and adjacent the extremities of'the support,enlargements 5 are formed. one of the said enlargements being providedwith teeth 6 formed at a point diametrically opposite to that face ofthe support having the blade 2 attached thereto,

A sliding guard plate 7 is arranged between the sides of the frame 1,the respective. extremities of the said plate 7 being provided withextensions 8 fitting grooves or slots 9 of the frame sides, the saidslots serving as guide means for the plate when moved or adjusted in amanner to be hereinafter fully described. An elongated roller 10,extending parallel with the support 4:, is journaled within bearings 11carried by the guard plate 7. Upon one end of the said roller 10 asegment 12 is mounted, the teeth of which, in the raised position of theguard plate. mesh into the teeth 6 of one of the enlargements 5, theteeth when meshing serving as a means whereby the blade and its supportmay be oscillated only to a certain degree. An arm 13 is rigid with thesegment 1; said arm working within a slot H of the guard plate, theterminals of the slot acting as stop means whereby movement of thesegment in a stropping operation is limited. Upon the opposite end ofthe roller 10 a cam head 15 is mounted, the said head being disposedbetween extensions 16 of a substantially U-shaped spring'l'f, theconnecting portion of which is rigid with the guard plate 7. By theprovision of the eucentric 15 and the spring 17, it is apparent that theroller 10 and the segment 12 carried thereby are at all times sopositioned relatively to the teeth of one of the enlargements 5 as tomove into mesh therewith when actuated. As illustrated to advantage inFig. 2, the guard plate 7 is semi-circular, one of the longitudinaledges being extended laterally as indicated at 18 to form a rest for theblade 2 when positioned foruse. Retaining lugs or lips 15) are rigid orintegral with the guard plate. 7, said lips being adapted fol-engagementwith the cutting edge of the blade to serve as a means whereby the bladeis held in place, flat upon the guard, when in use.

A hollow handle 20 is made fast to that portion of the frame designated1, said handle being hollow to receive the stem 21,

rigid at one end with the guard plate 7,.

ating screw 24 of a length sufficient to fit a threaded recess thereforwithin the stem 21 is so related withthe handle as to be turnabletherein, but incapable of longitudinal movement independent thereof. Asleeve or band 25, rigid with the'han-dle 20 at its free end, encirclesthe screw 21 and, as the said screw is constricted at this particularpoint,

longitudinal movement thereof, when turned, is impossible. Any suitableform of head or knob 26 may be provided for the screw.

When it is desired that the blade 2 be used for shaving purposes, theguard plate 7 is moved,-through operation of the screw 24, away from theblade support 4, whereupon the blade and its support are swung in thearc of 'a circle as indicated by the dotted lines" in Fig. 2 into theposition indicated in full lines therein, after which operation, thescrew 24 is reversely turned to move that portion of the guard plate 18into engagement with one of the lateral faces of the blade. 11'continued movement of the guard plate in a direction toward the supportwill position the cutting edge of the blade beneath the retaining lugs19, in which event oscillatory movement 'of the blade cannot beeffected, the 'blade being thus held rigidly ready for use.

Vhen a stropping of the blade is to be effected, guard plate 7 is againmoved, through operation of the screw, away from the blade, until theretaining lugs 19 are out of engagement therewith. Blade 2 is then swunginto the )osition indicated in dotted lines inthe said ig. 2, whereuponthe operating screw 24 is reversely turned until teeth of segment 12mesh into teeth (3 of one of the enlargements 5. \Vhen in mesh,oscillation of the blade during a stropping operation is limited by theterminals of slot 14, the arm or extension 13 of the segment beingengageable .first with one of the slot terminals and then with theother. Spring 17, by reason of its engagement with cam or eccentric 15at all times maintains segment 12 in proper position, and when the teethof the segment are already in mesh with the teeth 6 of the enlargement,serves as a means whereby the blade 2 is held alined with the frame 1and the handle.

It is to be understood that the strap, during a sharpening operation,may be arranged over the roller 10, between said roller .and the guard7, the razor suspended from ening of the razor may also be effected bysimply drawing the blade back and forth over a straight line strap andin amanner common to the art. a

From the foregoing, taken in connection with the accompanying drawingsit will be noted that the blade 2 may be positioned for stropping or foruse without removing it from engagement with its support; that ifdesired, throughmanipulation of a suitable screw 27, the blade may beremoved from its support and a new blade substituted therefor; and thatthe only operation necessary to'efl'ect the various adjustments of theguard plate is the turning ofthe operating screw24. 4

in reduction to practice, I have found that the form of my invention,illustrated in the drawingsandreferred to in the above description, asthe preferred embodiment, is the most elficient and practical; yetrealizing that the conditions concurrent with the adoption of my devicewi-llnecessarily vary, I desire'to emphasize the fact that various minorchanges in details of construction,-

proportion and arrangement of parts may be resorted to, when required,without sacrificing any of the advantages of my invention as defined inthe appended claims.

Having thus fully'described my invention, what I claim as new and desireto secure by Letters Patent, is:

1. In a safety razor, a hollow handle, a frame secured to said. handle,a rotatable support carried by said frame, a blade secured to saidsupport, a combined guide and guard movable relatively to said frame, -arotatable means secured to said combined guide and guard and turnablewithin said hollow handle to move said combined guide and guard, asegment mounted on said support, a'roller movable with said combinedguide and guard, a segment mounted on said roller for engagement withsaid first mentioned segment to oscillate said blade in one position ofthe combined guide and guard, and a means on said combined guide andguard to engage with the blade to lock said blade against movement,substantially as described.

2. In a safety razor, a movable blalde, a support therefor, teeth uponsaid support, a blade guard, an operating screw' actuatable to move saidguard, a segment carried by said guard, said segment being movable withsaid plate into and out of engagement with the teeth of said support,means integral with said segment and operating within a slot of saidguard plate to limit movement of the support and the blade In testimonywhereof I aflix my signacarrliledfthfireby, means o laaersilble tofillilfle thg ture in presence of two Witnesses.
